Answer:
A
Step-by-step explanation:
Given a quadratic equation in standard form : ax² + bx + c = 0
Then the discriminant Δ = b² - 4ac informs us about the nature of the roots.
• If b² - 4ac > 0 then 2 real, distinct roots
• If b² - 4ac = 0 then 2 real , equal roots
• If b² - 4ac < 0 then 2 non real roots
x² + 6x + 14 = 0 ← is in standard form
with a = 1, b = 6, c = 14, then
b² - 4ac = 6² - (4 × 1 × 14) = 36 - 56 = - 20
Since b² - 4ac < 0 then 2 non real roots → A

Answer:
1872 cm^3
Step-by-step explanation:
To solve this you can split the shape into two parts, the large rectangle with length 18 and width 8, and the small rectangle with length 6 and width 3.
So now apply the volume formula,
for the larger shape,
V = Area * height
V = L*W *H
V = 18*8*12
The volume of one part is 1728.
Now for the second shape on top,
V = L*W*H
V = 6*8*3 = 144
Now add the two, 1728+ 144 = 1872
1872 cubic centimeters
There are many ways you can start off by solving an equation. In this case, the first operation used in solving this equation would be subtraction. You would have to subtract 5 from each side.
